Explanation:
fluidity of an animal cell plasma membrane is enhanced by __________.
Answer:
Cholesterol molecules
Explanation:
Several factors increase the fluidity of the plasma membrane in animal cells.
First, by creating kinks in the lipid structure, the unsaturated fatty acids in the phospholipids that make up the membrane improve fluidity. Additionally, cholesterol contributes to the preservation of membrane fluidity. As a buffer, it reduces fluidity at high temperatures and prevents solidification at low temperatures. The actual temperature also has an effect on how fluid the membrane is at higher temperatures, the phospholipids move and flow more freely. Last but not least, the ratio of different phospholipids and their saturation levels can have an effect on the fluidity of the membrane.

the most significant difference between biofuels and fossil fuels is that biofuels are:
The most significant difference between biofuels and fossil fuels is that biofuels are: produced with biomass, that is, they are processed energy resources that come from organic compounds extracted from wild or cultivated plants.
Fossil fuels (such as oil, coal, and natural gas) are those that come from the natural decomposition of organic matter.
They are called non-renewable energies because they are limited natural resources since they require an extensive period of time and specific conditions to form.
On the other hand, a biofuel is a term that is used to refer to all those fuels produced from biomass, that is, through the chemical or physical treatment of organic or plant waste.
That is, unlike fossil fuels that come from energy stored for long periods in fossil remains, biofuels come from biomass, or organic matter that constitutes all living beings on the planet.
Biomass is a renewable energy source, as its production is much faster than the formation of fossil fuels.The use of biofuels as a renewable energy source can help reduce the consumption of fossil fuels, responsible for the generation of greenhouse gas emissions.During its production, part of the carbon dioxide that could be released into the atmosphere is extracted from the biomass.
For this reason, biofuels do not contribute to the emission of greenhouse gases.
Therefore, we can conclude that the most significant difference between biofuels and fossil fuels is that biofuels are: produced with biomass.

If an atom has 16 neutrons and atomic mass 31 it atomic is
Answer:
Mass number can vary due to the fact that the number of neutrons can vary. Isotopes are named for their mass numbers. So, this element has 15 protons (atomic number), 15 electrons, and 16 neutrons (mass number minus atomic number). This isotope is phosphorus-31, which has atomic number 15.

What is the name for a rise in temperature?The extremely quick rise in the average surface temperature of the Earth over the past century is known as global warming, and it is mostly caused by greenhouse gases that are emitted when people burn fossil fuels.
Highlights. Since 1880, the temperature of the Earth has risen by 0.14° F (0.08° C) per decade, but since 1981, the pace of warming has increased by more than twice that, to 0.32° F (0.18° C) per decade. According to NOAA's temperature data, 2021 was the sixth-warmest year ever.
The kinetic energy of a substance's particles rises as its temperature rises. Q. As the temperature rises, the particles' kinetic energy rises as well.
These dangers include sea level rise, which will cause coastal flooding and eroding, changes in the salinity of coastal groundwater supplies, which will cause freshwater stress, dangers to marine ecosystems, like mass coral bleaching and die-offs, and stronger tropical storms.

c) All of the choices are correct
Explanation:
Answer:
A. ( answer)
Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of DNA.
Explanation:
DNA replication involves several different enzymes. Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of the DNA molecule. Then an enzyme called DNA polymerase joins individual nucleotides together to form the new complementary strands of DNA. Lastly, the DNA polymerase "proofreads" each new strand to make sure that each DNA molecule is perfect, or a nearly perfect copy of the original molecule.
